3 Claims. (Cl. 135-5.1)

This invention has to do with means for suspending canopy when used for the purpose for which they are designed. An example of such an article is an oxygen canopy or tent which is suspended over a patient in bed. These canopies are often made of paper, plaster material and other sheet material which is apt to tear if subjected to undue strain. For example, oxygen tents, which are suspended from hangers above the patient and usually have loops of material attached at spaced points along their upper margins for this purpose, often tear at their points of suspension rendering the tents useless until repaired.

An object of this invention is to provide a new and improved oxygen canopy or tent. A particular object is to provide such a device having novel means whereby the same may be suspended and having a novel inlet sleeve construction.

Another object of the invention is to provide novel means of general use for suspending articles such as canopies and the like without danger of tearing or otherwise injuring the articles.

These and other objects will be apparent from the drawing and the following description thereof. Referring to the drawing, which is merely illustrative of a preferred form of my invention:

Fig. 1 is a perspective view of an oxygen tent or canopy embodying the invention.

Fig. 2 is an enlarged perspective view of one upper end portion of the canopy of Fig. l and a portion of the hanger.

Fig. 3 is a fragmentary perspective view of a corner of the device of Fig. 1 with the elastic band removed.

Fig. 4 is an enlarged sectional view on line 4-4 of Fig. 3; and

Fig. 5 is a fragmentary sectional view on line 5-5 of Pi 1.

%/Iore particularly describing the invention, the tent or canopy, generally indicated by 11, comprises an upper wall 12, a front side wall 13, end walls 14 and 15 and a rear side wall 16. This tent is adapted to be suspended over a patient in a bed fragmentarily shown at 18 by means of hangers 20 which are carried on a suitable rod 21 positioned adjacent the bed and extending over the same. Each of the hangers 20 terminates in a hooked end 22.

I provide novel means for suspending the canopy ll without injuring the walls thereof. In this connection it may be pointed out that the canopies are often made of thin sheet material, such as paper, or a vinyl-type plastic material, which does not possess great resistance to tearing. To suspend the canopy, I provide a plurality of strips generally indicated by 25 These may be made of a relatively strong material which may be fabric and by way of example may be a so-called binding tape. In the form of the invention shown, two such strips are used. Referring now to Figs. 2, 3 and 4, each of these strips 25 comprises a central portion 26 which extends across and beneath the upper wall 12 of the canopy, looped portions 27, and end portions 28. The strips 25 each extend through openings 30 in the sides of the canopy Y the strip passes the .istrip doubled :upon itself .at .each end :to form theailoaps 27. T The end :portions. 28 :are i brought down inside the side wall of the-.canopy and securedztheretaas by stitching 32. I also secure the end portions of the strips to the central portion thereof in the region where through the opening 30 as by means of a stitch or thread 33. The thread 33 also preferably extends through the upper wall 12 of the canopy. However, in this connection it should be pointed out that considerable slack is provided in the wall 12 between the points of securing the same to the strip 25, or, in other words, there is an excess of material between these two po nts in the upper wall over that in the strip so that the strip may be pulled taut without affecting the upper wall or placing any strain thereon.

Although it is not essential, I prefer to provide each of the looped ends of the strips with an elastic band 34 which is secured to the looped end of the strip by a conventional knot 35.

It will be apparent that the bands 34 may be hooked over the hooks 22 at the ends of the hangers 20 and that the strips 25 can be pulled taut and serve to support the weight of the canopy without placing any pulling strain upon the canopy.

It may not be necessary to utilize the strip-type suspension throughout, and in Fig. 1 I show the canopy as being provided with a pair of loops 40 formed of fabric which is merely stitched to the sides and top wall of the canopy.

It is also a feature of the invention that I provide a novel inlet sleeve which receives the inlet conduit 45 suplying gas to the canopy. In the particular construction shown, referring now to Figs. 1 and 5, the end wall 15 is provided with a pair of openings 46. About each opening there is secured a tubular section of material which may be of the same material as the body of the canopy. The tubular section may be secured by stitching 48. The tubular section 47 includes elastic band 50 which serves to effect a seal between the sleeve and the inlet pipe 45.

Preferably, all seams are welded as well as being sewn.

Although the invention has been particularly illustrated and described, it is contemplated that various modifications can be made without departing from the scope of the invention as set forth in the claims.

I claim:

1. In a canopy or the like formed of thin sheet material and having a pair of laterally spaced side walls depending from an upper connecting wall, means for suspending said canopy, comprising a plurality of spaced strips of material extending across said upper wall beneath the same and passing through said side walls, said strips each having its end portions turned back and secured to the adjacent side wall forming a loop outwardly of said side wall, and means securing said turnedback end portions of each strip to the main portion thereof in the region of the side wall.

2. In a canopy or the like formed of thin sheet material and having a pair of laterally spaced side walls depending from an upper connecting wall, means for suspending said canopy, comprising a plurality of spaced strips of material extending across said upper wall beneath the same and passing through said side walls, said strips each having its end portions turned back and secured to the adjacent side wall forming a loop outwardly of said side wall, and means securing said turnedback end portions of each strip to the main portion thereof in the region of the side wall, and securing said upper wall to said strip with said upper wall having an excess of material over that of the strip longitudinally of the strip between the points where the same is secured to the strip whereby to permit of said strip being pulled taut without tensioning said upper wall.

3. A canopy of thin sheet material comprising an upper wall, side and end walls depending from said upper wall, and canopy suspending strips extending across said upper wall beneath the same and passing through said side walls, said strips terminating outwardly of said side walls, said strips each having its end portions turned back and secured to the adjacent side wall, forming a loop outwardly of said side wall, and means securing said turned Patented Nov. 16, .1954,
